Estimation question

Estimate the Number of Orders delivered by Swiggy per hour in India

Practice this question out loud. An AI interviewer asks it, follows up like a real interviewer would, and scores your answer. Type or speak.

What this question tests

Estimation combining market size, ordering behavior, and operational scale reasoning.

Anchor on Swiggy's approximate scale in India, say 20 million monthly active users across major cities.
Assume a fraction order on a given day, say 10 percent, giving roughly 2 million orders per day.
Distribute orders unevenly across a day, with peak lunch and dinner hours capturing most volume, say 60 percent in a 4 hour window.
Calculate peak hourly rate: 1.2 million orders in 4 hours gives roughly 300,000 orders per hour at peak.
Calculate an average hourly rate across the full day: 2 million over roughly 16 active hours gives roughly 125,000 per hour.
Present both a peak and average estimate, since 'per hour' is ambiguous without specifying which.

Distinguishes peak hour from average hour explicitly, since food delivery has sharply uneven demand across the day.
States each assumption clearly, MAU, order penetration rate, and peak concentration, rather than a single unexplained guess.
Gives round, defensible numbers and shows the arithmetic so the interviewer can follow the logic.
Sanity checks the peak number against known restaurant capacity constraints in dense cities.

Giving a single flat number that ignores the large gap between peak and off peak hours.
Skipping stated assumptions and jumping to a final number.
Using implausibly precise figures with no rounding or range.
